SHEET-DELIVERY APPARATUS FOR PRINTING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 398,642, dated February26, 1889.

Application filed March 21, 1887.

"0 (177 717mm it may concern;

lie it known that I, ROBERT MIEHLE, of j Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Improvementsin Sheet-Delivery Apparatus 1 for Printing-Marinnes, of whichthefollowing is a specification.

The present invention relates to sheet-dclivery for cylinderprinting-presses in which the sheet can be delivered at the front or topof the cylinder; and it consists of two sets of revolvingdelivery-grippers or delivery-cylinders for delivering the sheet to thefiy frame.

In the accompanying drawings, Figure 1 is part of a side view inelevation of a two-revolution cylinder printing-press with the improvedsheet-delivery attached thereto. Fig. 2 is a front view of the same.Fig. 3 is a side View of one of the adjustable reels. Fig. 4 is asectional end view of the second deliverycylinder.

A designates the main frame of the press; 13, the i111pression-cylinder;B, the feed-board, and B the cylinder-grippers. In the frame A ismounted shaft D, upon which are secured brackets 0., holdingdelivery-rod a supporting the delivery-grippers or sheet-lifters on.These grippers take the sheet from the impressioncylinder, through theaction of the usual spring, a and cam a, by the wiper a of crank a,rolling upon cam a. The reels D upon shaft D support the sheet as it ispassed to the delivery-cylinder E, which has grippers 1) upon rod 1;,which are operated, througl'i spring b and cam 19 by the wiper 19 uponthe crank rolling on cam b The fly-frame or receiving-fingers G are heldupon rod G", which is journaled in frame A at the front end of thepress; The mechanism for operating the fly-fingers it is thought iunnecessary to show, as this operation is well- 1' known.

Motion is commu nicated to the deli very-cylinders by gearing, which isbut partly shown to more clearly show the other parts of the device.

The portion marked r on the impressioncylinder shaft U meshes with thegear w on the shaft D. This in turn meshes with the parts 50, this beingthe gear secured upon the shaftof the delivery-cylinder E.

The delivery of the sheet is as follows:

Serial No. 231,786. (Nu model.)

1 After the sheet has been printed and is brought around by theimpressioncylindcr grippers 13', the delivery-grippers or sheetlifters aseize the forward edge of the sheet and carry it around to the uppercylinder, E, the grippers 7) of which then seize it and carry it aroundthe top of the cylinder and discharge it upon the fly-fingers G, theends of which bear against he cylinder E, as shown in Fig. 4-, the saidfingers stripping the sheet from the cylinder as it. continues torevolve. The sheet is then lifted bodily by the fly-fingers anddeposited upon the receivingtable G It will be noticed that when theopen part of the cylinder E is at the point shown in Fig. 1 thefly-fingers G rest upon rod 1 which brings the end of fingers G belowthe periphery of cylinder E, and as the cylinder is moved forward theend of fingers G will ride upon the incline g, which insures the sheetbeing passed over the fingers. The pulleys 2 serve to assist the sheettraveling down the flyfingers. The same receive motion from gear N, aportion of which is shown in Fig. 1 and wholly in Fig. 2. This gearmeshes with gear :2: and communicates motion to gear N upon rod 1'. Theriding-pulley I, secured on rod 0, which has a rubber surface, alsoserves to assist the sheet traveling down upon the flyfingers, and isalso used for cutting the sheetby placing a circular knife thereon whichere tends into a groove cut in the cylinder E.

In order to remove the reels readily whenever desired, (as in most casesthey are en tire] y dispensed with,) the shaft .1) is cut away, as shownin liig. 3, to allow the reel (which has its hub cut away) slipping overthe same, enough of the hub being left to secure the reel with theset-screw upon the shaft 1).

The opening in the hub of reel D is suiticient to clear th e bracketsa,which are secured 3 This allows the reels to be 1 adjusted lengthwiseupon shaft D.

i The reels D may in some cases be substil l l l to the shaft 1).

tuted with a cylinder like cylinder E, or cylinder E may be substitutedwith reels, whichever way desired. Motion may also be comtuted insteadof the fiy-fingers G to remove away from the fingers, substantially asdethe sheet from the delivery-cylinder or reels scribed.

E, or the said cylinder may be set at any point around the sheet liftersor grippers without departing from the spirit of my invention.

hat I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with the impressioncylinder, of a series ofrevolving sheet lifters or grippers, and a receiver cylinder 'jonrnaledat the front or top of the linder to seize the edge of the sheet anddeliver it to adelivery cylinder, said deliverycylinder discharging thelast (or freshly) printed side away from the receiving devices,substantially as described.

The combination, with the im rn'essioncylinder, of a series of revolvingsheet lifters or grippers, a revolving delivering-cylinder andreceiving-fingers journaled at the front or top of the cylinder to seizethe edge of the sheet and deliver it to a revolving deliverycylinder,which in turn delivers it to a series of fingers with the last orfreshly printed side i l i a. The combination, with theimpressioncylinder, of two sets or series of revolving sheet lifters orgrippers j ournaled at the front or top of the cylinder, and a reel orreels revolving with said grippers to support the sheet as it isdelivered to the second set of delivery-reels, the same delivering thesheet to the receiving devices with the last or freshly printed sideaway from the same, substantially as described.

4. The combination of the impression-cylinder, sheet-lifters a, delivery-cylinder E, flyfingers G, and pulleys i, substantially as andfor the purpose set forth.

5. The combination of the impression-cyli nder, revolving sheet-liftersa, del i very-cylinderor reels E, strippin g-fingers G, and pulleys i, i
